The document discusses how buzz monitoring and measuring social media impact is evolving to become more comprehensive. It notes that while public social media is easily monitored, offline and "dark social" conversations are larger in volume and growing faster. These private conversations differ in their triggers, participants, and nature. The document advocates measuring total social performance by combining offline word-of-mouth surveys with online social listening. Some brands also perform differently across online and offline channels. As people's lives increasingly blend online and offline interactions, it is important for social measurement and activation to consider all channels rather than just the visible public conversations.
